Hence, it will be clear that the preparation sprayed within the closed, Fig. 1 is a sectional view, showing the cabinet cannot escape readily and will be impmved spraying device as applied t t n tained within the cabinet for a greatly increased or other part of a cabinet, wardrobe, or the like; pe iod of time, thus greatly increasing e e Fig. 2 is a side view of the air blast tube, with fectiveness of the sprayed preparation. the cap of the receptacle and the feed tube 66 While the spraying elements disposed within which will hereinafter appear and be set forth in theclaims appended hereto.

In the accompanying drawing, wherein an the cabinet are shown as projecting from a flat wall thereof, it will be clear that they may be otherwise located so as not to encroach upon the containing area or storage space in the cabinet. For example, the spray nozzle and the receptacle ll maintained thereby, might be located in a corner of the cabinet or at any other convenient location.

The passage l9 through the air tube is relatively small in diameter and therefore the escape therethrough of the sprayed preparation is very slow. However, even this slight escape of the sprayed material can be prevented if desired, if the nipple portion l2 on the outside of the cabinet is capped by a thread-on cap as soon as the pump I4 is detached at the end of the spraying operation. A valve might also be provided by means of which the passage l9 could be closed upon the detachment of the pump M, thereby confining the sprayed preparation within the cabinet.

In use of the device, the cabinet can be packed with the garments or other articles, and the door or other closure for the cabinet can then be closed or even sealed. The pump is then attached by threading the nozzle portion 4 3 onto the threaded end l2 of the air tube 5, and the pump is operated externally of the cabinet to the extent required to thoroughly spray the interior of the closed cabinet. At the completion of the spraying operation, the pump is detached and if desired, the passage 19 closed by a thread-on closure cap applied to the end l2 of the tube 5 if a complete closure of the cabinet is desired. From time to time, as the occasion requires it, the interior of the cabinet can be sprayed, each time the operation being performed as above described and without requiring the opening of the cabinet, this not being required until it is desired to remove the contents of the cabinet or until the contents of the receptacle II are depleted.

While I have herein shown a certain way of securing the air tube in place, and have shown said tube and associated parts of a certain design, wherein the tube is contracted as at 4 and has a narrowed portion 8 to which the cap 9 is attached, a difierent form of spraying means might Well be used and the same might be otherwise attached to the cabinet. The primary result sought is the provision of means by which a cabinet or other closed container can be effectively sprayed exteriorly of the container thus confining the sprayed preparation within the container, and this attained by the structure disclosed and set forth in the claims appended hereto.

What I claim is:

1. In a sprayer attachment for cabinets, chests or other closed containers, the container having a fixed wall provided with a tubular passage extending through it and having one end communicating with the exterior of the container, a liquid container located within the cabinet and having a spray tube located at the inner end of the passage whereby air delivered through the latter will spray the liquid throughout the interior of the cabinet, the second end of the passage being located on the outside of the cabinet and having means for detachably receiving and supporting a hand-operated air pump and permitting hand operation of the pump and spraying inside of the cabinet without requiring opening of the door thereof.

2. A sprayer attachment for spraying the inside of a closed cabinet provided with a fixed cabinet wall comprising, a tube passing through said wall, a liquid-holding spray receptacle contained within the cabinet and supported therein adjacent to the inner end of the tube, the tube having an outer end located on the outside of the cabinet, a hand-operated air pump provided with coupling means by which it is coupled to and supported by the outer end of said tube, said pump whenso coupled to the tube being capable of operation to thereby spray the interior of the cabinet while the cabinet is in a fully closed con dition.

3. A sprayer for, closed cabinets and the like having a wall, an air tube mounted in the wall and having its outlet end located within the cabinet, said tube being connected to a liquid-holding container also located within the cabinet, the air tube passing through the wall of the cabinet and being provided with means located on the outside of the cabinet for coupling it to a pump for the forcing of air by said pump through said tube while the cabinet is completely closed and by operation of said pump on the outside of the closed cabinet.

4. A sprayer as provided for in claim 3, wherein the air tubeis a threaded element and is held by nuts in the wall of the cabinet, and the air tube has a threaded portion on the outside of the cabinet, and the pump is threadably attached to said threaded portion on the outside of the cabinet.
